Chrysanthemum plant named ‘CIDZ0091’

ABSTRACT

A new  Chrysanthemum  plant named ‘CIDZ0091’ particularly distinguished by the purple and white bicolor, daisy-type inflorescences, excellent flower production, strong growth and spreading plant habit, and very uniform flowering with response time of 8 weeks when grown under short days.

Latin name of the genus and species of the plant claimed: Chrysanthemum x morifolium.

Varietal denomination: ‘CIDZ0091’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum x morifolium, and hereinafter referred to by the variety name ‘CIDZ0091’.

‘CIDZ0091’ is a product of a planned breeding program. The new cultivar has purple and white bicolor, daisy-type inflorescences, excellent flower production, strong growth and spreading plant habit, and very uniform flowering with response time of 8 weeks when grown under short days.

‘CIDZ0091’ originated as a naturally occurring whole plant mutation discovered among flowering plants of ‘B8040’ growing in a greenhouse in Gilroy, Calif., in January 2014. The parent is the proprietary unpatented breeding line ‘B8040’, and having inflorescences of a dark purple hue under usual conditions, while it is similar to ‘CIDZ0091’ in all other characteristics.

The first act of asexual reproduction of ‘CIDZ0091’ was accomplished when vegetative cuttings were propagated from the initial selection in April 2014 in a greenhouse in Gilroy, Calif.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated August, 2014, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘CIDZ0091’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘CIDZ0091’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar has not been applied for. ‘CIDZ0091’ has not been made publicly available prior to the effective filing date of this application, notwithstanding any disclosure that may have been made less than one year prior to the effective filing date of this application by the inventor or another who obtained ‘CIDZ0091’ directly from the inventor.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘CIDZ0091’ with colors being as true as possible with an illustration of this type.

The photographic drawing shows in FIG. 1 a close-up view of the inflorescence of the new variety and in FIG. 2 a whole flowering plant grown in a greenhouse.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions and measurements were taken indoors in Gilroy, Calif. in January 2017 on about 12 week old plants. Unrooted cuttings had been planted, 4 plants per pot, in 6 inch pots on Oct. 24, 2016. The plants were pinched and moved to short days on Nov. 14, 2016 to induce flowering.

The aforementioned photographs: FIGS. 1 and 2 were taken in Gilroy, Calif. in January 2017, and showing a plant from a trial, in which flowering had been induced by applying black cloth.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
